To all wle/0m it may con/cern,.- n

Beit known that vLGEonGn B. ESSEX, a citizen of the United States of America, residing at Detroit, in the county of lVayneand State of Michigan, have invented certain new and useful Improvements in Lubricators, of whichthe following is a specification, refer: ence being had therein to the accompanying drawings. v l. 1

My invention relates more particularly to improvemen tsjin locomotive-engine lubricators; and it consists in the improved construc-A tion and arrangement' of parts, fully set forth hereinafter and shown in the accompanyingdrawings, in whichf l Figure lis a rear elevation of my improved luhricator. Fig. 2 is a horizontal section thereof on line 2 2, Fig. 1. Fig. 3 is a horizontal section thereof on line 3 3, Fig. l. Fig. Il is a vertical central section on lines 4: d, Figs-.-

angles to Fig. l with some parts shown in vertical section. V l k- In the accompanying drawings, A is the oilf cup, provided with the usual waste-cock c at thehottom, the fil1ing plug o in the topthe screw-nipple c on the side for screwing the Connected to the top of the oil-cup is the condenser B, which has a discharge-piped leading down to near the bottom of the oil-cup, and C C C2 are three upward-dowsight-feed tubes communicating through the usual discharge-tubes c with the interior o f the oil-cup, under control of the usual regulating-valvesf The sight-feed tubes have the usual oil-*noz-l zles and are provided with lateral outlets or feed-arms D D' D2, which have suitable coup-Y ling-nipples g for connecting them to the tallo w-pipes,which respectively connect the out lets D D with the steam-chests of the locomotive-cylinders and the outlet D2 with the airbrake engine. As will be seen, the outlet D? is placed on the same vside of the oil-cup as the outlets D D' by meansvof a duct h', leading from the top of the sight-feed tube C2 through Fig. 2. ,v

The parts as described above are all of the usual construction and operation and do not form any part of my invention.

n The condenser Yhas a hollow head E, made slain N5. l715,021. un ms.)

of a separate casting screwed into the top of `the condenser and forming an induct for the steam into the condenser, suitable coupling means being provided for connecting it with the source of steam direct from the locomotive-boiler. Within this head, on the upper sidethereof is cast a steam-chamber fi, around which the steam can freely pass into the coni denser and which communicates through a port t" atits underside with the steam-induct. This port i is controlled by a check-valve t2, which is guided by a valve-stem i5 in a guide hearing of the hollow screw-plug t?, The plug t? has connected. to it an equalizing-pipe F,

. which'through passages i* communicates with the steam-induct and leads to the feed-arm D?, as clearly shown in Fig. 4." The steam'- chamber il has Aopenings K on opposite sides which lead through passages Y across `the spacci-between the walls of the steam-chamber and the head into couplingnipples jj, (see Fig. 1,) to whichare connectedthe auxiliary pipes H H. `These auniliary pipes connect with the feed-arms D D" in the following manner, particularly shown y in'Fig.` 5, in .connectiony with the feedarm D,

in which l is an upwardly-*extending branch y of said feed-arm divided hy a transversepartition Z into two separate passages mit.. The partition Zextends across the feed-arm and divides it into two chambers 0 p. The cham- ,ber 0 comm unicatesvwith the sightfeed tube through a port q and contains a hall-valve r, normally resting ina depression of the chamber and adapted to close the port q upon the reliefvof-Vpressurein the sightfeed tube, as will occur when the glass should be broken. The chamber p communicates with the charnher o through the nozzle s, which is formed with a tubular perforated extension s', formedY with the shoulder s2 at itsY base, which seats the nozzle in an opening inthe partition' l, and with the Aflaring rim s3, 'by means4 of which the nozzle isremovably clamped in position by the coupling membersggg'` of the tallowpipe. The passages m nterminate in coupling-nipples tt.' To the former the auxiliary pipe'H is coupled, and to the latter is coupled IOO an equalizing-pipe J, which yleads from the head E. The feed-arm D' is constructed in the. same manner as the feed-arm D and provided Withan auxiliarypipe H and equalizing-'pipe J. The feed-arm D2 connects with the top of the sight-feed tube C2 through a horizontal tube h, (see Figs. 2 and 4,) which is preferably cast integral with the oil-cup in such manner that the passage through it may be formed by drilling from opposite ends. This arm D2 is also formed with a chamber u, communicating through the port u' with the sight-feed tube C2 and inclosing a ball-valve u2, which normally rests in a depression on the bottom of the chamber u and is adapted to close the port u upon a relief of pressure, as in the case of the breaking of the sightfeeditube. The equalizing-pipe F, already described, is connected into the top of this chamber, and into the outlet leading from this chamber into the fallow-pipe is secured the nozzle QJ.

Into the top of the oil-cup is secured a screwplug G, formed with a vehrtical passage, communicating at the lower end with the top of the oil-cup and dividing on top into two horizontal passages w', each of which is controlled by a regulating-valve L. The passages w" lead in opposite directionsl and are connected by means of stub-pipes tu? and suitable coupling-nipples to the passages n of the oil-feed branches I. In this manner auxiliary oil-passages (orso-called blind 7feed-passages) are formed from the oil-cupinto the feed branches D D', and thus it either of the two sight-feed glasses should break the sight-feed can be cut out by closing the regulating-valve in the bottom and opening the valve L leading to the same feed-arm, the ball-valve in the feed-arm being seated automatically by the relief of the pressure on thc breaking of the glass.

The oil-feed arms D D at their inner ends communicate with pockets M, cast in the interior of the oil-cup, and inthis manner the walls of the pockets absorb heat from the steam admitted into the oil-feed arms and keep the oil in the cup Warm. The connection h also tends to keep the oil warm.

In the axis of the condenser is mounted the valve-spindle M', which has a screw-threaded guide-bearing X, and passes out through stufing-box in the head E. The lower end of the spindle is formed with a taper seat adapted to seat upon the discharge-outlet fy, formed in a screw-plug y, which secures the discharge-pipe d to the condenser.

In the practical operation of my lubricator, which is of the Well-known type, in which the lubricant is gradually flooded out ofthe oil-cup into the tallow-pipes by the water of condensation from the condenser, which receives a constant supply of steam from the boiler through a connection with the head E, the steam is directly admitted into the chamber i, and thus has a short unobstructed iiow by way of the ports K, auxiliary steam-pipes H, and passages m into the talloW-pipes at their junction with the feed-arms D and D and through the talloW-pipes into the steamchests, thus carrying the lubricant discharged from the oil-cup along with it and preventing any stoppage from condensation, as the quantity ot' steam thus fiowing produces overpressure in said pipes. `Then the steam is shut off, however, for stopping lthe locomotive, it is obyious that as the momentum of the train keeps the engine still running it will draw a supply of steam into the cylinder through the auxiliary steam -pipes H, and thereby cause a sudden relief of pressure therein, which seats the valves 2.

The arrangement of the chamberi prevents it from being flooded by Water of condensation, nor will it be robbed ot' its supply of steam by the equalizing-pipes, which are of lesser size than the pipes H.

The auxiliary or blind oil-feed provided by means of the passages w, w', w2 and n is ob.- tained in a simple and reliable Way, and its use Whenever occasion demands does not disturb the equalization of pressure within the lubricator.
